This paper synthesized three kinds of ionic liquids, there are [C14EIM]Br, [C16EIM]Br and [C18EIM]Br respectively. Then use the FTIR to characterize of chemical structures. Also study the effect of ionic liquids with different length of carbon chains to intercalated sodium montmorillonite. The results shown that the ionic liquids synthesized were the target products. The result of XRD shown that the ion exchange reaction between ionic liquid and the sodium montmorillonite could occurred, and the more numbers of carbon atoms of the ionic liquid, the longer the chain, the greater the distance of montmorillomote.

Reaction Equations

To reduce environmental pollution from dyeing wastewater, reverse micelles were prepared and used for the removal and separation of anionic Color Index (CI) Reactive Yellow 3 and cationic CI Basic Red 14 in mixed dye aqueous solution. The effect of the amount of dye and surfactant on removal rates of dyes was investigated. An ion-exchange reaction model was used to fit the experimental data. Ultraviolet-visible absorption spectra were employed to evaluate the state of dyes in mixed dye aqueous solution during the removal process. In addition, the removed dyes were recovered by back extraction and reused for dyeing fabrics. The results obtained indicated that the removal of dyes was increased with increasing the amount of surfactants, while the dye concentration exhibited the reverse trend. The dye extraction process could be described by the ion-exchange reaction equations. The mixed dyes could be removed and separated for the attractive force between dyes and the counter ionic surfactant. The mixed dyes were separated and recovered, which exhibited a good dyeing property.

Ion Exchange Reaction

The formation of reactive oxygen species due to irradiation by a visible light of the polythiophene deposited in ZSM-5 zeolite channels in aqueous medium has been studied. Polymerization of thiophene was carried out in zeolite channels after the ion-exchange reaction of Na+ for Fe3+. By means of EPR spectroscopy, the temporarily generated 1O2 in irradiated aqueous medium was proved. The formation of O2-• was confirmed by the reduction of Fe3+-cytochrome c. Irradiation led to the water reduction to hydrogen.
